Our Departments
AC Stators
The AC Stator team provides the expertise required to rewind any stator; repair and recondition core laminations, insulations, housings, liners, flanges, terminals and lead wires; as well as install and repair terminal blocks and current transformers.
AC Rotors
Highly trained repair technicians disassemble, reinsulate, rewind and repair main rotor assemblies; recondition laminations, insulations, windings and lead wires; repair loose cores, damaged shafts, bands, carriers, diodes and various hardware; perform complex assembly procedures; balance and overspeed as required.
Roundwire
This department can decipher the most challenging wiring schemes and rewind units using gauge sizes of 12 to 38, including: exciter stators, exciter rotors, PMG’s, roundwire armatures, stitch-wound stators, and other various units.
DC Stators
With many years of collective experience, these technicians have developed creative strategies and techniques to rewind and recondition series, interpole, compensation windings and insulations; shim poleshoes; repair leads, main and brush terminals (crown repair), end bell assemblies, housings, and terminal blocks.
DC Armatures
From disassembling; re-insulating; installing coils, commutators and rings; to brazing, dipping, undercutting and balancing, our dynamic team of armature repair technicians yields an incredible output of armatures a month.
Coils
Our specialty Coils is the one of the reasons for our great quality. Each Coil is crafted to spec. and undergoes through a series of inspections before installed on the units.
Specialized Departments
Our modern 20,000 square foot facility has all the latest equipment,
technology, design approval and engineering to ensure the highest standard of quality for our customers.
With over 60 highly skilled technicians, we work meticulously throughout all stages of the Rewind
and Repair process with a commitment to servicing the aviation industry worldwide.
Quality Control and Assurance
Equipped with the latest instrumentation, tools and sophisticated test equipment, our Q.C./Q.A. department is capable of accurately sampling, inspecting, and testing components to assure that they conform to OEM—defined specifications.
Engineering
Our qualified engineers are capable of reverse engineering nearly any generator subcomponent. Using sophisticated CAD software, rewind/repair manuals are created, which are then approved by a Transport Canada delegated engineer (D.A.R.). Upon approval, all components are listed in our capabilities.
Plating & Grinding
PRS’s highly skilled and fully certified technicians are capable of performing Nickel, Cadmium and Copper plating processes in accordance with AMS 2451, MIL-STD-865C and MIL-STD-2197. Through the use of computer—driven controllers, our technicians can perform grinding operations within ten thousanths of an inch tolerance.
Machining
Through the use of both modern machinery and state of the art computerized automation, our highly skilled technicians can provide a range of precision machining functions including: cutting, milling, boring, tapping, turning and grinding.
Brazing
We have developed a new, custom—made brazing machine, which can accommodate a range of brazing and soldering applications. Its highly efficient design produces reliable, smooth and uniform joints.
Balancing
In addition to our Dynamics Research DSP-100 balancing machine, our newly acquired Schenck-Trebel HM2BK machine has doubled our output of precision—balanced rotable components.
Overspeeding
Our overspeed capabilities have been recently increased to achieve speeds of up to 45 000 RPM.
Coil Manufacturing
Through comprehensive research and development, our engineering team has designed a computer—driven pneumatic coil manufacturing line, which provides a range of process functions including wire feeding, spreading, shaping, cutting, stripping and winding.
Research & Development
Our federal SR & ED Research & Development department presses forward with the latest advances in industry-specific technologies, with the aim of improving existing processes and advancing knowledge within the aircraft industry.
